Unable to render paginated reports with optional (blank) Parameters

As of yesterday Dec 7th, users are unable to execute pagination reports in the Power BI service and receive an error saying parameter values have not been specified for optional (allow blank) parameters.  There are no hidden parameters.


Multiple reports across multiple Workspaces are impacted and no changes have been made to the reports.  Re-uploading one of the reports using Report Builder makes no difference - the error still shows:


Unable to render paginated report

One or more parameters required to run the report have not been specified. The parameter(s) "OrderNumber", "Surname", "Firstname" has missing values.

Status code: 200
